I received the 30pk for my baby shower, which is actually a better price at $21.97 (not a dollar per bag as mentioned by one reviewer). I find these very easy to use and I much prefer the Munchkin's diaper pail over the Genie 2. I also found them to be effective in trapping in smells. I haven't tested on diapers yet as I'm due Dec. 27, but we tried it out with our two dogs' business and it worked fairly well.
